我需要删除或更改函数“obtener_info”的标签，我不知道如何在 tkinter 中更新或删除带有条件的标签。有人知道怎么做吗？ 这是我的代码，我正在使用 pyserial 和心跳传感器。这是一个学校项目。

我在每个条件下都放置了一个 label.configure，现在它会更改 arduino 的每个更新。这是更新的代码。
if genero == "femenino":
label_estado = Label(NewWind, text="Su estado de salud es ", font="Century_Gothic")
label_estado.place(x=100, y=100)
if edad == "20 a 29":
if bpm >= 78 and bpm <= 94:
label_estado.configure(text="Su estado de salud es optimo")
elif bpm < 78 or bpm > 94:
label_estado.configure(text="Su estado de salud es no optimo")
